Differential lipid species identified during HCV infection: Mock and HCV-infected Huh7 cells (2 h, 10 h, and day 7) were used for differential analysis of lipid species where panel (a,b) shows PLS-DA score plot between selected PCs from positive and negative ion mode, respectively. (c,d) Features identified by sPLS-DA model for a given component. Variables are ranked by the absolute values of their loading scores. The colored boxes on the right indicate the relative concentration of metabolite under study. The red color indicates highest concentration and blue indicates the lowest concentration of the metabolite under this study.
